Icon Audio Stereo 40 MkIII 2A3 Integrated Valve Amplifier 

Please Note Various upgrades are available across the range of Icon Audio Valve Products. Please call for details and prices.

For those seeking the ultimate in high definition and smoothness without high power the 2A3 is an ideal valve. The very special 2A3 is a pure triode valve very similar to the WE 300B (1937) but pre dating it by seven years. When designing an amplifier it is not just about using good components but getting the “synergy” right, so music does not sound mechanical or contrived.

17 Watts may not sound a lot, but with average efficiency speakers will fill a normal sized room with power to spare.

The 2A3 is relatively undemanding of the driver stages and power supply, and with valve costs at around half the price of the 300B, means that a true “High End amplifier can be produced for a reasonable price, without any compromise.

The basic chassis of Icon Audio's Stereo 40 series is exactly what they need using specially designed power and output transformers. Again the older, bigger 6SL7 and 6SN7 valves have the exact qualities needed and also benefit from being more rugged and longer lasting.  

The brand new design is finished with a fine metallic paint work that is easy to clean and is wear resistant. A 10 mm solid alloy front panel with polished dark chrome alloy knobs. And Icon Audio's attractive Plexiglas valve cover to create a stunning visual impression. On the scales at 25Kg, most of this weight is the higher than normal grade of iron they use. And the transformers are wound with 4N copper (99.9999% pure).
